Project Spotlight: Immortal, Quad Mech

Wednesday, February 23rd, 2011

Cire came to our forums with a background in mechanical engineering and an insatiable urge to get involved with Mech Warfare. Inspired by Starcraft 2, he wanted to build a Mech that was based on the Protoss ranged support unit, the Immortal. He did his research, started with rough 3D CAD drawings, and ultimately decided to use AX-12+ Dynamixels & the Arbotix Robocontroller with it’s NUKE engine as a basis for his platform.

His project thread documents the progress he made, from someone with minimal previous electronics and programming knowledge, to someone with a highly competitive and fully functional Mech Warfare platform. Aesthetically this quad Mech hits the mark perfectly with its custom machined aluminum frame; Immortal is only very polished project that is sure to prove a fierce competitor at Robogames this April. Cire also went the extra mile and integrated a 4th degree of freedom in each leg; the position of the tip of each leg uses the angle values of the rest of the leg to maintain a perpendicular orientation to the ground. Be sure to check in with the competition results to see how he fares at Mech Warfare 2011!

2010 Contest Winners Announced!

Friday, February 11th, 2011

First of all, I have to apologize for the delay in getting the results posted. We have been unbelievably busy in the last 2 months (mostly due to the content of our previous blog post) and wanted to make sure we could put aside the proper amount of time and effort to judge our numerous entries.

We judge contest entries in 3 different areas on a 1-10 scale:

1) Ingenuity

2) Originality/Creativity

3) Presentation, Documentation, & Explanation!

However in addition to simply voting this year the TR crew sat down, threw back a few beers, and discussed why we had our top picks. Rather than simply give a numeric score as the basis for winning, I took notes on that discussion and want to convey our thoughts in cliff-note form as I feel they provide feedback to not only the contestants that won, but also others who will enter in our future contests. One thing to keep in mind is that even if your project did not win this time, if you continue to improve and further document your project you are eligible for re-entry in our future contests.

So without further ado, here are the top 3 Contest Winners!

Third Place:

Project - A PLM mech for MW
Creator - jes1510
Prize - Roboni-I
Why it won: jes1510 took a newer concept (PLM) that had been discussed pretty thoroughly here on the TRC, prototyped it using Bioloid components and a bit of hacking, and then blew us away with a ground-up hand built metal chassis. This gave us a really nice peak into how he planned out this project and made it a reality. The hand metal-work is top notch as well! Even though this project is still a work-in-progress, it’s an excellent show of pioneering a relatively new leg design from concept to proof-of-concept to final version.


Second Place:

Project - Hi No Hikari
Creator - darkback2
Prize - Headplay VR Goggles
Why it won: darkback2 took PLM and decided to run with it as well. He was actually the first person on our forums to dive in and start building after our fairly feverish discussion in the PLM Discussion Thread. He absolutely excelled in documenting his progress, success, and failures. He actively discussed it with the community, took feedback into consideration, and continued to improve the project and push it forward. Somethings would go wrong, but he would quickly come up with a solution and keep pushing on. This is a pretty familiar process to tinkerers in general, and hit home nicely with the judges. Did we mention the entire bot was built using a drill press, vice, and jig saw? Definite bonus points for the DIY approach. Again- the huge number of progress updates as the project developed and community interaction made this project score very highly.


First Place:

Project - Archer – an IK controlled biped
Creator - Zenta
Prize - InterbotiX PhantomX Hexapod Kit
Why it won: Zenta is pretty famous about these parts- a few years back he nabbed First prize for his Phoenix Hexapod entry which had some of the most impressive IK and smooth motions we’d ever seen. He pretty much conquered Hexapod Inverse Kinematics, so he moved on to the next challenge: Biped IK. In terms of raw technical expertise, Archer is one of the most advanced robots we’ve seen on the TRC. Bipedal IK is not an easy thing to solve, and not only did he pull it off perfectly, the end result and overall smoothness in Archer’s movements is unrivaled. On top of that, he implemented a COG (center of gravity) shifting device that is absolutely brilliant. The videos demonstrate this robot’s capabilities perfectly, and consistent project updates as well as a full release of all of his code is what landed Zenta first place here. He set the bar pretty high with this entry, but with an open source offering we hope other’s can learn from the knowledge he shared with this project. Congratulations to Zenta for the truly awe inspiring project!


Well that’s it for this round folks! We’ll be sure to keep you guys updated on when the next round of projects will start. Until then, keep building!

Editors Note: Three bipeds won? Seriously? We haven’t had a single biped place in top 3 in the last 3+ years this contest has been running, and this year we had not one but three bipeds place? Wow. Someone better make sure Giger hasn’t killed off the TR crew and replaced us with his humanoid brethren.

Hall 1 – IRC Korea 2010

Monday, December 13th, 2010

Some of you saw the Diary Of A Mad Roboticist! post 2 months ago where Andrew and I were getting ready to fly over to Korea and do some humanoid competing. As usual we were biting off way more than we could chew and were building robots up until hours before leaving on a 22 hour trip.  It turned out we were being over zealous as usual too, because the competitions were way more chill than what we expected. So we spent much more of our time meeting people and exploring the wonders of Korea than competing. Andrew did get to do some exhibition matches with the local college students and Giger fell over a lot. Andrew also got a lot of R&D time in with a future humanoid code named Shadow Blade (Video) (all RX-24F servos!) which should be on shelves in 2011. Andrew ALSO did a lot of work on the RX-24/28 PLM robot also coming out in 2011 which will be a “soldier” series bot specifically designed for fighting. Coming later-ish maybe… a 3rd video of Andrew and I exploring Korea. That video needs, um, editing due to copious amounts of soju being consumed during the making.

Robot World 2010 – Robot eye candy galore

Wednesday, November 24th, 2010

As many know, we were recently at IRC 2010 in Korea. What even we ourselves didn’t know is that Robot World was going to be in Hall 2 right next to us. Robot World was packed full of amazing robots. Almost no one spoke English so we can”t tell you what they do, but we did run around taking lots of pictures and video to bring back for everyone. Enjoy, and try not to drool on your keyboard. One thing is clear, Korea knows how to make some cool robots.

Livestream of Friendly Match Between RoboCup World Champions

Thursday, November 18th, 2010

SK. of the DarmstadtDribblers Robocup team fame dropped by our forums to let us know that a friendly match is being streamed live between his team and the champion team from the Standard Platform League, B-Human. It should start in TEN minutes (it’s 9:49am CST at the time of writing. We’ll see if we can also get a youtube link to this for those that miss out, should be pretty interesting to watch!

During the farewell-reception of SIMPAR2010 the acting RoboCup world champions from the Standard Platform League (B-Human, DFKI and Univ. Bremen) and the Humanoid Kid Size League (Darmstadt Dribblers, TU Darmstadt) will play a friendly exhibition match. Since two years, both teams have not lost a single game in their leagues. However, now both teams will play this test match on a mixed field with mixed rules of both leagues using the SPL ball.

IRC2010 in Korea- Too Much Robotic Awesome For One Show.

Tuesday, November 9th, 2010

We’re still reeling from our trip to Korea; jet-lag, last minute flu bugs, and a tad too much Soju really did a number on us. One thing is for sure- Asia has the US beat handily on robotic presence. What we didn’t know when heading to the competition was that IRC2010 also was attached to Robotworld 2010, the single largest Robotics Convention we’ve ever seen. Literally hundreds of booths and double or even triple that number of robots ran wild in a convention hall bigger than an aircraft hanger. It’s going to take us a few weeks to sort through all the video, but we’ll give you a sneak peak at the hundreds of pictures we took. There is some SERIOUS robot-eye-candy in these galleries, be sure to check it out.

Hall 1 Gallery – This is mostly the competition pictures.

Hall 2 Gallery – This is the convention hall. They had robots we didn’t even know existed.

And here’s a few choice pics for those of you too lazy to check out the above linked galleries!
